Cobham SAILOR 4065 Emergency Positioning Indicating Radio Beacon, GNSS/AIS - Manual
An EPIRB is used to alert search and rescue services in the event of an emergency. It does this by transmitting a coded message on the 406 MHz distress frequency via satellite and earth stations to the nearest rescue coordination centre. Some EPIRBs also have built-in GPS, which enables the rescue services to accurately locate you to ±50 metres.
406 MHz EPIRBs work with the Cospas-Sarsat polar orbiting satellite system, giving true global coverage. There is an alert delay of about 45 minutes, dependent on when the satellites come into view on the horizon with the current LEOSAR and GEOSAR constellations. With the new MEOSAR constellation, which is currently being installed, the goal is to achieve instantaneous detection. The MEOSAR constellation is up and running, with the full system working by 2021.
The messages sent from the beacon are coded messages that allow the receiving rescue authorities to identify the vessel to which the beacon belongs. The additional information attached to the vessel, such as emergency contact information, can then be accessed via the registered details.
This allows the rescue authorities to get in touch with the relevant parties to determine whether the alert is false or genuine. Most EPIRBs include a 121.5 MHz frequency, which is used for “homing” purposes. When the rescue services are in the region, this frequency allows them to determine the direction of the signal.
